17 00 009 Checking cooling system for leaks (N54, N52K)
| WARNING | Danger of scalding! Only perform this work after engine has cooled down. |
Protective measures/rules of conduct
- Wear protective goggles
- Wear protective gloves
- Observe national/country-specific regulations
| IMPORTANT | Risk of slipping due to coolant on the floor. Danger of injury! |
Catch and dispose of drained coolant in drip tray (1) and if necessary special tool 00 2 030 (universal hydraulic lifter).
Recycling
Observe country-specific waste-disposal regulations.
Scheme 66
Checking pressure drop in cooling system
Open cap on coolant expansion tank. Fit special tools (1) 17 0 101 and (2) 17 0 113.
Build up GAUGE PRESSURE and wait approx. 2 minutes.
Cooling system is impervious to leaks if pressure drop is max. 0.1 bar.
Scheme 67
Checking pressure relief valve in cap
Note. While the vehicle is driven at high outside temperatures, the design may cause the pressure relief valve in the cap to open slightly and air together with dissolved coolant to escape. This coolant vapor condenses on the surface of the expansion tank and leaves traces when the vehicle has cooled down. These traces do not indicate whether the cap is defective or not. When the vehicle has been parked up for an extended period of time, the residual escaping coolant can cause the pressure relief valve in the cap to stick; therefore check the cap again 2 to 3 times.
Replace the cap only after you have checked three times and there is an incorrect opening pressure.
Screw cap (1) onto special tool 17 0 114.
Build up pressure with special tool (hand pump) 17 0 101; observe pressure gauge to ascertain when opening pressure is achieved.
Compare OPENING PRESSURE of pressure relief valve.

17 00 008 Draining and adding coolant (N52K)
| WARNING | Danger of scalding! These tasks on the cooling system should only be carried out on an engine that has cooled down! |
| IMPORTANT | Lifetime coolant filling: Never reuse used coolant! When replacing and removing components which rely on the corrosion protection effect of the coolant, it is essential to change the coolant. The cooling system must therefore be drained and refilled. |
In the case of other removal work involving the draining of partial quantities of coolant, replace these quantities which have been drained with new coolant.
Installation
Use only recommended coolant.See COOLING SYSTEM - OPERATING FLUIDS .
Observe mixture ratio.
Protective measures/rules of conduct
- Wear safety goggles
- Wear protective gloves
- Observe national/country-specific regulations
| IMPORTANT | For dirt contamination of the cooling system (e.g. by engine oil), the cooling system must be rinsed with water until all dirt contamination is removed! |
| IMPORTANT | Risk of slipping due to coolant on the floor. Risk of injury! |

17 00... Instructions for working on cooling system
| WARNING | Danger of scalding! Work on the cooling system should only be carried out when the engine has cooled down. |
| IMPORTANT | Wear protective gloves and safety goggles. |
| IMPORTANT | Lifetime coolant filling: Never reuse used coolant. When replacing and removing components which rely on the corrosion protection effect of the coolant, it is essential to change the coolant. The cooling system must therefore be drained and refilled. |
In the case of other removal work involving the draining of partial quantities of coolant, replace these quantities which have been drained with new coolant.
| IMPORTANT | Open cooling system only when it has cooled down. Opening the cooling system while hot can result in air entering the system. This can cause overheating with permanent damage to the engine. |
| IMPORTANT | You must protect the alternator against contamination before carrying out any work on the cooling circuit. Cover alternator with suitable materials. Failure to comply with this procedure may result in an alternator malfunction. |
| IMPORTANT | Do not fill coolant expansion tank over MAX level as overfilling will cause the coolant to overflow. This may give rise to traces of residual coolant on the expansion tank or in the engine compartment and wrongly suggest possible leakages. |
Recycling
Catch and dispose of drained coolant.
Observe country-specific waste-disposal regulations.
Note. To disconnect coolant hoses, use commercially available disconnect tools such as HAZET brand tools (see table).

| WARNING | If the engine hood/bonnet contact is pulled upwards (workshop mode), the information "switch closed" is output. The automatic engine start-stop function is active. An automatic engine start is possible. |
Observe safety precautions when working on MSA vehicles
Before carrying out practical work on the engine, always ensure that the MSA functionality is deactivated so as to prevent automatic engine starting while work is being carried out in the engine compartment.
MSA function is deactivated by
- Deactivate MSA by means of button (1) in passenger compartment
- Open seat belt buckle and driver's door
Scheme 80
- Open engine bonnet/hood and ensure that engine hood/bonnet contact is not in workshop mode
- Workshop mode A = 10 mm
- Basic setting (engine hood/bonnet open) B = 7 mm
To make sure that the engine hood/bonnet contact is at the basic setting, if necessary press the hood/bonnet contact up to the limit position before starting work and slowly release.
